EYEGLASSES.

SPECIFICATION forming part of Letters Patent H0. 730,459, dated. June 9, 1903. Application filed February 13; 1903. Serial No. 143,209. (No model.)

part of this specification,and represent, in-

Figure 1, a front view of apair of eyeglasses having my improved spring applied thereto; Fig. 2, a top view of the same; Fig. 3, a sectional view on the line a b of Fig. 1, showing a side view of my improved spring; Fig. at, a

perspective view of the spring detached. The

figures are all on an enlarged scale.

This invention relates to an improvement in eyeglasses, and particularly to the springs therefor, the object of the invention being the construction and arrangement ofa spring which will not project above the upper edges of the lenses and yet which will have sulficient length to permit necessary adjustment; and the invention consists in the construction as hereinafter descrihed,and particularly recited in the claim.

As herein shown, the central portion A of the spring is longitudinally bowed and centrally arched. The sides B of the spring extend downward at substantially right angles to the central portion and parallel with each other, and from these sides the ends C extend upward, the ends,which are wider than the intermediate portion of the spring, having perforations D,hy which the spring is secured to the usual logs or posts E, which support the lenses F, the eyeglasses being provided with the usual nose-clamps G, which may he of any approved construction, the sides Band ends 0 being so proportioned and arranged that the lower end of the sides B extend just below the lower edge of the posts E, the said sides extending upwardly in line with but in rear of the posts and between the posts and guards, and the bowed portion extends forward directly above the posts, beyond which it is upwardly arched. By forming the spring, as shown, with the upwardly-extending ends I obtain suflicient length of metal to give the requiredamonnt of spring, and by turning the ends of the spring downward and thence upward provides for as much adjustment as is ever required. I

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination with the lenses, posts and guards of eyeglasses, of a spring the central portion of which is longitudinally bowed and npwardlyarched, the sides of the spring turned downward in rear of the posts in the plane of the outer ends thereof and-between the posts and guards into line with the lower] I edges of said posts, the endsof said spring extending forward beneath the said posts and above the lower end of the guards the extreme ends of the springs extending across the ends of the post and perforated for attachment j thereto, substantially as described.

In testimony whereof 'I have signed this specification in the presence of two subscribing witnesses.

. CARL F. INGOLD.
